JESSE H. IEERRAULT, or DETROIT, MICHIGAN.

PAEERBQTTLE AND OPENER.

Specification of Letters Patent.

Patented May "2, 1918.

Application filed January 19, 1916. Serial No. 73,004.

To all whom it may concern 1 Be it known that I, JEssE H. PERRAULT,citizen of the United States, residing at Detroit, Wayne county,Michigan, have invented certain new and useful Improvements inPaperBottles and Openers, of which the following is a specification.

- This invention relates to improvements in paper bottles orreceptacles, and particularly to an improved means for readily openingor removing the caps therefrom.

The objects of this invention are:

First, to provide an efiective and-simple means for severing the wall ofa paper receptacle.

Second, to provide a form and arrangement of structures whereby theresult of severing or separating a part may be readily accomplished.

Further objects and objects relating to details and economies ofconstruction and operation will definitely appear from the detaileddescription to follow.

I accomplish the objects of my invention by the devices and meansdescribedin the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I milk bottle embodying the features of my invention in apreferred form.

Fig. II is an enlarged detail vertical sectional view taken on a linecorresponding to line 22 in Fig. I.

Fig. III is a detail sectional view taken on a line corresponding toline 3-3 of Fig. II, showing the formation and folding of the layers andthe disposition of the severing cord therein.

Fig. IV is a detail elevation view of my invention applied to a taperedcup structure.

-Fig. V is adetail sectional view taken on a line corresponding to line5-5 of Fig. IV, showing the arrangement of the parts and the dispositionof the severing cord therein.

Fig. VI is a detail sectional view taken on a line corresponding to line66 of Fig. V.

Fig. VII the layers of paper are folded back upon themselves to form theupper edge of the receptacle. I

Fig. VIII is a detail sectional view showing my invention as applied tothe straight 1 sides of a paper receptacle made up of sevis an elevationView of a papershows a modification in which' the separate drawing, 1 isthe body of a milk bottle or other jar made up of plies of paper 2, the

which are preferably disposed transverse. 3 is the neck conformed bycreasing and folding the paper together. 4 is the annular crease in theneck conformed at the inner side in angular form to receive the cap 5.All of the layers of paper are conformed to this crease (the creasebeing preferably formed by dies after the bottle is made) and within thecrease is disposed a waxed or oiled cord 6 which is securely retainedbetween the layers of paper with the outer end projecting. When it isdesired to remove the cap, as seen in Figs. I, II and III, theprojecting endof the cord is grasped by the user and it is simplyunwound, and because it does not adhere to the paper it readily cuts thewall ply by plyand severs the top, permitting the cap to drop freelywithout any necessity for punching or pulling of the parts. Thispresents a perfectly clean-cut pouring surface for the contents of thebottle, which is perfectly fresh cut and uncontaminated.

The thread being folded between the layers and assed around in thecreases, as indicated in Fig. III, is sufficiently retained so that itscutting action is very pronounced, and it readily severs the top asindicated. This can be applied to straight side jars, preferablycreased, where the convolutions of the folded parts are absent, as seenin Figs. IV and V. The action of the cor is greatly facilitated byconforming the annular groove with a sharp angular projection.

In Fig. V there are two layers 7 of the material and the cord 6 isdisposed between the same in' precisely the same manner as appears inFig. II, except there are no convolutions of layers.

In Fig. VII the cord is only disposed between the outer layers 8, theouter ply being folded back on itself at the top at 9, and the fibers ofsevered part is simply held to the outer I layers by a thin layer ofparafiin. It is ver readily separated when the outer layers have beencut by the cord.

With the straight walls seen in Fig. VIII, made up of layers 10 with acap 11,-it is necessary to dispose the cord in the concentric layers insubstantially the same plane,

so that it will only be necessary to draw the cord through a singlelayer of material at a time. It is less easy to effecti ely locate thecord in this structure, but it can be accomplished and will do its work,but not nearly so well as when disposed in the creases indicated in theother figures of the drawing.

These paper bottles and receptacles are parafiined and 4 the layers areretained together in part by the paraffin, and the effect of the same onthe plies of paper is to make them very readily severable by the waxedor oiled cord.

The disposition of the fibers transverse to the neck 01' body of thereceptacle facilitates the action of the cord, which is then a splittingaction as distinguished from a transverse cut. This is of highconsequence where the cord is made use of in such modifications asspecial groove has not been formed, although it is of advantage wherethe groove has been formed where the cord then operates with thegreatest facility. Of course it is of less importance that the cord bespecially waxed where it is disposed in the angular groove.

I have shown my invention in the form preferred by me, but I am awarethat it is capable of considerable variation without departing from thespirit of my invention,

and I desire to claim the same specifically in the form illustrated, aswell as broadly within the scope of the appended claims.

Having thus described my invention,.what I claim as new and desire tosecure by Letters Patent is 1. A receptacle made up of layers ofparaflined paper, with annular grooves formed therein with waxed corddisposed between the layers in the angular projections with a projectingend whereby the same may be withdrawn severing the successive layers foropening the receptacle, the annular groove.

2. A receptacle made up of layers of paraflined paper, with annulargrooves formed therein with angular projections,

ers in angular projections With a projecting same may be withdrawnsevering the successive layers for opening the receptacle.

3. A receptacle made up of layers of 7 paper, with annular groovesformed therein appear in Fig. VIII, where a' angular projections, a.

and a cap retained withinv with angular projections, a waxed corddisposed between the layers in the angular projections with a projectingend whereby the same may be withdrawn severing the successive layers foropening the receptacle, and a cap retained within the annular groove.

4. A receptacle made up of layers of paper with the fibers disposedtransersely to the receptacle, with annular grooves formed therein withangular projections, a cord disposed between the layers in the angularprojections with a projecting end whereby the same may be Withdrawnsevering the successive layers for opening the receptacle, and a capretained within the annular groove.

5. A receptacle made up of layers of paper,with annular grooves formedtherein with angular projections, and a waxedcord disposed between thelayers in angular projections with a projecting end same may bewithdrawn severing the successive layers for opening the receptacle.

6. A paper receptacle made up of layers of paper with the fibersdisposed transversely to the receptacleconformed and folded the one uponthe other, and a cord disposed in between the successive layers in thesame region, with a projecting end for cutting and severing thesuccessive layers for opening the receptacle.

7. A receptacle made up of layers of paper with the fibers disposedtransversely to the receptacle, with annular grooves formed therein withangular projections, a cord disposed between thelayers in the angularprojections ith a projecting end whereby the same may be withdrawnsevering the successive layers for opening the receptacle, and a capretained within the annular groove.
